ARC PROTECTION DEVICES

The atmospheric over voltages caused by lightning and, in some cases, network overloads may cause conductor breaks, particularly in the case of covered conductors and these are protected by arc protection devices.

We take this opportunity to introduce ourselves as one of the manufacturers & Suppliers of Polymer Insulators.

We are doing all the necessary Type tests & Design tests for Polymer Insulators for 11, 22 & 33 KV (Disc & Pin type) at CPRI-Bangalore & ERDA-Vadodhara.

Polymer Insulator is introduced as an excellent & proven technology, which is replacing the existing porcelain Insulators all over the world.

Due to its properties, technology, durability & other value added advantages some Electricity Boards in India also adopted this technology for their states. Power Grid Corporation of India, NTPC and Indian Railways had already started to install / replace the existing porcelain Insulators with Polymer Insulators. Polymer insulators have the following utilities:

• Light weight ( up to 70% less than Ceramic insulators). Ease of installation as easier to handle and transport.
• Outstanding resistance to environmental factors such as U.V. light , ozone, acids, contaminations and moisture.
• Silicone Rubber shed s provide perfect Hydrophobic performance, hydro-phobicity transfer in to pollution layer also possible, good resistance to ageing and tracking & erosion.
• Stable behavior at extreme climatic conditions -50 to + 50 deg C.
• Suitability for polluted and salty atmospheres etc.
• Resistance to breakage and vandalism , practically unbreakable.
• Eliminates or reduces maintenance ( such as washing) and are compatible with existing porcelain insulators.
• Energy Efficiency (Low leakage current due to more surface resistivity).
• Safety( Light weight for handling and installation, eliminates catastrophic mechanical failures).
• Consistent mechanical and electrical performance through out entire service life.
